Title: Natural flow and batch-like process for purifying water
Inventor: JIEFUAASON ERU GENTORII
IPC: C02F1/58
Filed: 1990-08-01
Abstract: PURPOSE: To enable easy batchwise cleaning of water in an arbitrary place by disposing means for supporting first and second chambers and a filter housing in a position where the water flows from the first chamber into the second chamber through a filter layer by gravity.  
     CONSTITUTION: A filter cartridge 30 is hung down from a supporting member 28 fixed to a funnel-like vessel 26. This vessel 26 is provided with a taper angle A in the outside diameter part and is therefore, stably supported in the aperture of a pot 12, etc. When raw water is injected into the funnel-like vessel 26 from the hole 34 of the cap 32 of the vessel 26, the water is passed through the filter cartridge 30 by gravity and the contaminants, such as lead, aluminum and chlorine, included in the raw water are decreased by filter pads 56, 58, 60. This water flows down into the pot 12. A relatively large volume of the water is thus cleaned batchwise in an arbitrary place.

Title: Thin film el display element
Inventor: HIRAI MASAAKI
IPC: H05B33/10
Filed: 1988-08-17
Abstract: PURPOSE:To prevent an extension of dielectric breakdown in aging by connecting in series to back plates resistors having resistances higher than those of the back plates, respectively. CONSTITUTION:Back plates I1, I2, I3 are connected to terminal electrodes H1, H2, H3 through resistors R1, R2, R3 having resistance values higher than those of the back plates. In the thus formed thin film EL display element 12, it is assumed that a dielectric breakdown shown by the line l2 is caused, for example, between the electrodes I1 and I2. In the aging of the element 12, when a positive pulse voltage is applied to the terminal H1, the pulse voltage is sent to the electrode I1 through the resistor R1 and to the electrode I2 through the resistor R2. The electrode I2 is connected to the electrode H2 through the resistor R2. Thus, as the current is sent through the resistors R1, R2, only a minute current is sent to the line l2, and the extension of dielectric breakdown can be prevented.

IPC: G01N27/41
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To accurately detect sensor element resistance regardless of the scattering of various primary factors such as the detection timing of the amount of current change with voltage change and a time constant. SOLUTION: An A/F sensor 30 outputs a linear A/F detection signal being proportional to oxygen concentration in an exhaust gas being discharged from an engine 10 with the application of voltage. A bias command signal Vr outputted from a microcomputer 20 is converted to an analog signal Vb by a D/A converter 21 and is inputted to an LPF 22 for eliminating the high-frequency components of the analog signal Vb. An output voltage Vc of the LPF 22 is inputted to a bias control circuit 40. When element resistance is detected, a signal where a specific time constant is given by the single AC voltage of a specific frequency range at the LPF 22 is applied to the A/F sensor 30, and the element resistance is detected according to then voltage change and current change.  At this time, the application time of voltage being switched by giving the specific time constant is set to a value that is longer than time when a peak current is generated after switching the voltage.
